XLamp® ML-B LEDs
PRODUCT DESCRIPTION
The XLamp® ML-B LED brings lighting-
class reliability and performance to 1/4-
watt LEDs. The XLamp ML-B LED expands
Cree LED’s lighting-class leadership to
linear and distributed lighting applications.
With XLamp LED lighting-class reliability, a
wide viewing angle, uniform light output,
and industry-leading chromaticity binning
in a 3.5-mm X 3.5-mm package, the XLamp
ML-B LED continues Cree LED’s history of
segment-focused product innovation in
LEDs for lighting applications.
The XLamp ML-B LED brings high
performance and a smooth look to a wide
range of lighting applications, including
linear lighting, fluorescent retrofits and
retail-display lighting.

Notes:• Cree LED maintains a tolerance of ±7% on flux measurements, ±0.005 on chromaticity (CCx, CCy) measurements and ±2% for CRI measurements.
See the Measurements section (page 19).• XLamp ML-B LED order codes specify only a minimum flux bin and not a maximum. Cree LED may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.• Typical CRI for Cool White (4300 K – 8300 K CCT) is 75.• Typical CRI for Warm White (2600 K – 4300 K CCT) is 80.• Minimum CRI for 80-CRI White is 80.• Minimum CRI for 85-CRI White is 85.• Minimum CRI for 90-CRI White is 90.

TYPICAL SPATIAL DISTRIBUTION
THERMAL DESIGN
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for the end
product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life
and optical characteristics.

REFLOW SOLDERING CHARACTERISTICS
In testing, Cree LED has found XLamp ML-B LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed below. As a
general guideline, Cree LED recommends that users follow the recommended soldering profile provided by the manufacturer of the solder
paste used, and therefore it is the lamp or luminaire manufacturer’s responsibility to determine applicable soldering requirements.
Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment.
Profile Feature Lead-Free Solder
Average Ramp-Up Rate (Tsmax to Tp) 1.2 °C/second
Preheat: Temperature Min (Tsmin) 120 °C
Preheat: Temperature Max (Tsmax) 170 °C
Preheat: Time (tsmin to tsmax) 65-150 seconds
Time Maintained Above: Temperature (TL) 217 °C
Time Maintained Above: Time (tL) 45-90 seconds
Peak/Classification Temperature (Tp) 235 - 245 °C
Time Within 5 °C of Actual Peak Temperature (tp) 20-40 seconds
Ramp-Down Rate 1 - 6 °C/second
Time 25 °C to Peak Temperature 4 minutes max.
Note: All temperatures refer to topside of the package, measured on the package body surface.
Note: While the high reflow temperatures (above) have been approved, Cree LED’s best practice guideline for reflow is to use as low a
temperature as possible during the reflow soldering process for these LEDs.

NOTES
Measurements
The luminous flux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specifications only
and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number
of factors that are not within Cree LED’s control and are not intended or provided as operational specifications for the products. Calculated
values are provided for informational purposes only and are not intended or provided as specifications.
Pre-Release Qualification Testing
Please read the LED Reliability Overview for details of the qualification process Cree LED applies to ensure long-term reliability for XLamp
LEDs and details of Cree LED’s pre-release qualification testing for XLamp LEDs.
Lumen Maintenance
Cree LED now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen
maintenance. For information on the specific LM-80 data sets available for this LED, refer to the public LM-80 results document.
Please read the Long-Term Lumen Maintenance application note for more details on Cree LED’s lumen maintenance testing and
forecasting. Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive
current affect the LED junction temperature.
Moisture Sensitivity
Cree LED recommends keeping XLamp ML-B LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately prior
to soldering. Unopened MBPs that contain XLamp LEDs do not need special storage for moisture sensitivity.
Once the MBP is opened, XLamp ML-B LEDs should be handled and
stored as MSL 2a per JEDEC J-STD-033, meaning they have limited
exposure time before damage to the LED may occur during the soldering
operation. The table on the right specifies the maximum exposure time
in days depending on temperature and humidity conditions. LEDs with
exposure time longer than the specified maximums must be baked
according to the baking conditions listed below.
Baking Conditions
It is not necessary to bake all XLamp ML-B LEDs. Only the LEDs that meet all of the following criteria must be baked:
1. LEDs that have been removed from the original MBP.
2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above.
3. LEDs that have not been soldered.
Temp.Maximum Percent Relative Humidity
30% 40% 50% 60% 70% 80% 90%
35 ºC - - - 17 1 .5 .5
30 ºC - - - 28 1 1 1
25 ºC - - - - 2 1 1

XLamp® is a registered trademark of Cree LED. UL® and the UL logo are registered trademarks of UL LLC.
CLD-DS39REV 9A 20
LEDs should be baked at 70 ºC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from the MBP before baking. Do
not bake parts at temperatures higher than 70 ºC. This baking operation resets the exposure time as defined in the Moisture Sensitivity
section above.
Storage Conditions
XLamp ML-B LEDs that have been removed from the original MBP but not soldered should be stored in one of the following ways:
• Store the parts in a rigid metal container with a tight-fitting lid. Verify that the storage temperature is <30 °C, and place fresh desiccant
and an RH indicator in the container to verify that the RH is no greater than 60%.
• Store the parts in a dry, nitrogen-purged cabinet or container that actively maintains the temperature at <30° and the RH at no greater
than 60%.
• For short-term store only: LEDs can be resealed in the original MBP soon after opening. Fresh desiccant may be needed. Use the
included humidity indicator card to verify <60% RH.
If an environment of <60% RH is not available for storage, XLamp ML-B LEDs should be baked (described above) before reflow soldering.
RoHS Compliance
The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to as the threshold
limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2011/65/EC (RoHS2), as
implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree LED representative or from the Product
Ecology section of the Cree LED website.
REACh Compliance
REACh substances of very high concern (SVHCs) information is available for this product. Since the European Chemical Agency (ECHA)
has published notice of their intent to frequently revise the SVHC listing for the foreseeable future, please contact a Cree LED representative
to insure you get the most up-to-date REACh SVHC Declaration. REACh banned substance information (REACh Article 67) is also available
upon request.
UL® Recognized Component
This product meets the requirements to be considered a UL Recognized Component with Level 4 enclosure consideration. The LED
package or a portion thereof has been investigated as a fire and electrical enclosure per ANSI/UL 8750.
Vision Advisory
WARNING: Do not look at an exposed lamp in operation. Eye injury can result. For more information about LEDs and eye safety, please
refer to the LED Eye Safety application note.
